exception exposed this - m_pCodeManager is not properly DACized. A pointer with a vftable need to be DACized using VPTR so that the DAC magic can translate the vftable properly.

Handling of hardware exceptions had a hack to add +1 to the actual instruction IP. Windows x64 unwinder
is disassembling instructions at the IP passed in to detect method epilogs. If the bytes at IP + 1
happened to match the epilog pattern, the unwind is done as if we were in the middle of the epilog that
lead to spectacular crash.
This change is moving this adjustment to be done later for EH related things only, and not interfere
with stackwalking.
Fixes #2535

Thunk
This broke debugger stepping through interface dispatch in some circumstances
[tfs-changeset: 1618045]

Move to using the Universal Thunk for cases where we need to perform complex lookup to perform interface dispatch. This allows us to permit exceptions to occur in interface processing without ripping the process down. As a side benefit, we are able to reduce the amount of platform specific assembly code needed to build the product. NOTE: CoreRT still uses the old managed callout logic, as I don't have time on my schedule to write a SYS V ABI version of the universal transition thunk.

Today, we assume that funclets are separate methods, in the sense that they get unique unwind information, but that's where the separation ends. They are still tightly coupled to their "parent method" in other ways. One of those couplings is the fact that they must be laid out contiguously with the parent method. These changes update the EH dispatcher and the ICodeManager abstraction to allow for funclets to be disconnected from their parent method. This mostly falls into the category of using addresses instead of offsets when referring to handlers and when handling the special case of "remapping" a hardware fault location to a safe point in an associated handler.

This change modifies PAL_LIMITED_CONTEXT, StackFrameIterator and REGDISPLAY
structs and also all related code accessing registers that are not present
for Unix.

These changes are targeted at completing/hardening the runtime's
support for the new UniversalTransition and CallDescr thunks and also
clarifying the invariants that hold throughout stack walker operation.
